How to Enable Mono Audio in Windows 10
- To access the Accessibility features on your Android device, open the Settings app.
- In the Settings app select Accessibility from the list.
- Now scroll down to the Audio & on-screen text section and select Mono audio to set the toggle switch to On.
Windows lets you convert stereo sound into a single channel so you can hear everything, even if you’re using just one headphone. Select the Start button, then select Settings > Ease of Access > Audio, and then switch on the toggle under Turn on mono audio.
